I'm using this piece of code to export in current.txt a text line corresponding to the sequence in the loop:

Code:
awk "NR==$sequence{print;exit}" $file > /var/www/html/current.txt

Problem is that if i run it from browser doesn't seem to work (txt file does not modify, stays the same, showing first line); in shell code works as expected.
I've tried double-quoting, single-quoting the variable without succes.

Any ideas what am i doing wrong, or another option to do this?

ppmquantall(1)						      General Commands Manual						    ppmquantall(1)

NAME
ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap SYNOPSIS
ppmquantall [-ext extension] ncolors ppmfile ... DESCRIPTION
Takes a bunch of portable pixmap as input. Chooses ncolors colors to best represent all of the images, maps the existing colors to the new ones, and overwrites the input files with the new quantized versions. If you don't want to overwrite your input files, use the -ext option. The output files are then named the same as the input files, plus a period and the extension text you specify. Verbose explanation: Let's say you've got a dozen pixmaps that you want to display on the screen all at the same time. Your screen can only display 256 different colors, but the pixmaps have a total of a thousand or so different colors. For a single pixmap you solve this problem with ppmquant; this script solves it for multiple pixmaps. All it does is concatenate them together into one big pixmap, run ppmquant on that, and then split it up into little pixmaps again. (Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option to separately quantize each pixmap to that set.) SEE ALSO
ppmquant(1), ppm(5) BUGS
It's a csh script. Csh scripts are not portable to System V. Scripts in general are not portable to non-Unix environments. AUTHOR
